Larry Cooper, one of the driving forces behind the 2014 ballot initiative to require GMO labeling in Colorado, is urging Colorado’s U.S. Sen. Michael Bennet to maintain a vigil on a federal proposal to block states from addressing genetically modified foods.

He took issue with criticism of Bennet leveled by Farm Bureau Colorado President Don Shawcroft on March 16. Bennet voted against the legislation, because he thinks a better bill can come from a pending compromise, his office said.
